A device called the charcoal canister, which stores fuel vapors when the engine is off, is the heart of the EVAP system<\/a>. Once the engine is running (and conditions are correct), our friend the purge valve opens, allowing fuel vapors to be pulled into the engine’s intake manifold<\/a>, where they’re burned as part of the normal combustion process. <\/p>\n\n\n\n
If the purge valve is stuck open, vapors from the charcoal canister can sneak into the intake manifold during refueling, making the vehicle difficult to restart. <\/p>\n\n\n\n
On your vehicle, the purge valve is located near the throttle body. You could try testing the valve, but it might be more efficient to just replace it and see if that helps. The valve is relatively inexpensive and easy to replace. <\/p>\n\n\n\n
Good luck!<\/p>\n\n\n\n

Q: I have a 2010 Hyundai Accent GLS with a 1.6L Engine. The vehicle is difficult to start after refueling. Once the car has been driven for a few minutes, it operates normally, and any subsequent starts are normal. What could be the problem?<\/h2>\n\n\n\n
